1. What is located at the fifth intercostal space?: Apex of the heart
2. Apex of the heart: tip of the heart pointing down toward the 5th left
intercostal space
3. Which layer of the heart allows it to act as a pump?: Myocardium
4. Left ventricle: What is the hardest working cardiac chamber and
therefore has the thickest myocardium?
5. Which layer of the heart wall contains the epicardium?: pericardium.
6. pericardium: surrounds the heart
7. Which of the following is related to the mitral valve?: Bicuspid
8. Which of the following contains oxygenated blood?: Pulmonary veins
9. Coronary arteries: Which of the following supplies oxygenated blood to
the heart muscle?
10. Myocardium: Which layer of the heart has actin, myosin, and troponin?
11. coronary arteries.: What is the next step in the sequence of the blood
flow: Blood flows from the left atrium to the left ventricle to the aorta to
which of the following structures?
12. Oxygen poor Carbon dioxide rich: Select all that apply >>>Which
features are true of blood leaving the tissues, travelling towards the right
atrium?
13. pulmonary capillaries.: What is the next step in the sequence of the
blood flow: Blood flows from the right atrium to the right ventricle to the
pulmonary artery to which of the following structures?
14. left ventricle.: From which structure does the aorta receive blood?
15. pulmonary veins.: Which vessel carries blood from the pulmonary
capillaries to the left atrium?
16. Right atrium: Which cavity of the heart first receives unoxygenated
blood from the vena cava?
17. Tricuspid: Blood flows from the right atrium through which
atrioventricular valve to the right ventricle?
1/6
, 18. Aortic: What is the name of the valve that prevents backflow of blood
into the left ventricle when the left ventricle is in diastole?
19. Tricuspid Mitral: Which valves are open during atrial systole
20. pulmonic valve: right semilunar valve separating the right ventricle and
pulmonary artery
21. What is the function of the pulmonic valve?: To prevent the flow of
blood from the pulmonary arteries to the right ventricle during ventricular
diastole.

fibers to the heart?
26. SA node: Where does the cardiac action potential (cardiac impulse)
normally originate?
27. RA: The pacemaker of the heart is located in the myocardium of which
chamber?
28. conduct electrical signals throughout the ventricles.: What is the
function of the Purkinje fibers
29. : Which of the following vessels carries unoxygenated blood from the
liver to the inferior vena cava?
Correct Answer:
Hepatic veins
30. inferior vena cava.: Where is blood pressure the lowest?
31. RA: The blood flows from the axillary vein to the subclavian vein to the
brachiocephalic vein to the superior vena cava. Where does the blood flow
next?
